We chose Sunlight Contractors after thoroughly researching the market, and we’re so glad we did. From the very beginning, Ira and his team stood out with their excellent communication and transparency. They gave us all the information we needed to make an informed decision, even sharing what to look out for if we ended up going with another company. We needed old insulation removed, but Sunlight also gave us great advice about additional steps we might want to consider, like treating the wood to protect it moving forward. They spent a lot of time helping us think through the project and discussing different options to make sure it would be a success. Sunlight provided a great estimate, and on the day of the job, the crew arrived on time and were incredibly professional and friendly. They worked with care and efficiency, and we were so impressed by their attention to detail—especially how thoroughly they cleaned up after a big job on such a hot and humid day. We were very happy working with Sunlight Contractors and wouldn’t hesitate to work with them again in the future. Highly recommend!

After our house was damaged by a motor vehicle accident, we contacted sunlight contractors to help us with the repair. They did an inspection and also gave us excellent referrals for people in unrelated areas of house maintenance. Ira and his team were very communicative, always respectful, and always looking out for the best for us and our home. During the work, the damage was noted to be more extensive than previously thought. Ira would call me and keep me up-to-date, and we got through these difficult times respectfully as a team. They let me know what was most important, were understanding of our financial situation, and were not quoting additional unnecessary services to price gouge us. The final product is beautiful, you could never tell that the house went through an accident. I would 100% recommend Ira and sunlight contractors for any repair. This is a honest, hardworking, and skilled contractor company.

My wife and I purchased a home in 2020 and were recently devastated when finding out we had a mold/moisture issue in our sub-flooring as a result of improper spray foam installation that resulted in costly damage. Ira Bosh and Sunlight Contractors came highly recommended and we were able to get a very fast and fair quote with a plan to remediate our issues. Ira's communication and knowledge have been exceptional thus far. He and his team were able to start repairs immediately and he has been in contact with us each day with updates and photos. He has been extremely kind and patient, explaining each step and answering any questions. We would highly recommend Sunlight Contractors to anyone in a similar situation.

I cannot say enough wonderful things about In Tech Insulation and its owner, Greg. From start to finish, Greg proved to be honest, extremely knowledgeable, and genuinely dedicated to the quality of his workmanship. It’s rare to find someone who takes this much pride in what they do, and it shows in every step of the process. Before any work began, Greg took the time to fully evaluate my home, discussing in detail what was needed and why. He carefully listened to my concerns and made sure I understood all of my options. What impressed me even more was the way he coordinated with the other contractors involved. He didn’t just show up and do his part—he communicated thoroughly with everyone to ensure that the entire team was aligned and working toward the same goal. My home was built in 1900, which meant it required several different types of insulation to be effective. Greg approached the project with exceptional skill and attention to detail. The results speak for themselves—my home is more comfortable, efficient, and protected than it has been in years. I highly recommend In Tech Insulation to anyone seeking a professional who truly knows his craft, stands by his work, and delivers outstanding results. If you want honesty, expertise, and pride in performance, look no further than Greg and his team!

Niki and Ricky were very knowledgeable and helpful as they made my house more energy efficient. They both thanked me for welcoming them into my home when they were the ones doing a service for me. The things they pointed out to me were very important and informative. They fixed the issues they found and this service was completely free. I am most grateful that they took the time to test so thoroughly for any interferences with my duct work that were affecting my air condition units. I highly recommend you contact Niki and Ricky with Diversified Energy for your home.

I will definitely recommend them to everyone I know and use their services again!!

Frequently Asked Questions — Spray Foam Insulation in New Orleans

These are the questions New Orleans homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 30% typical energy savings. Compare the 6 verified New Orleans contractors above for exact quotes.

Is spray foam insulation a good choice in hot and humid climates like New Orleans?
Absolutely. Hot and humid climates like New Orleans, LA are actually where spray foam insulation delivers some of its best results. Closed-cell spray foam acts as both an insulation layer and a moisture/vapor barrier, preventing the humidity infiltration that causes mold, rot, and air conditioning inefficiency. Homeowners in LA typically see 20–35% reductions in cooling costs after installation. One important note: because spray foam creates a tight building envelope, proper mechanical ventilation is essential in humid climates to manage interior moisture from daily activities like cooking and bathing.
What type of spray foam is best for homes in New Orleans?
In hot and humid climates like New Orleans, LA, closed-cell spray foam is generally recommended for exterior walls, crawl spaces, and attics. Its high density creates a moisture barrier critical in humid environments. Open-cell foam can be used in interior walls for soundproofing and actually allows some vapor movement, which can be beneficial in certain wall assemblies. A qualified local contractor can assess your specific home and recommend the best approach.
Can spray foam insulation help reduce my AC bills in New Orleans?
Yes — significantly. Air conditioning accounts for the majority of energy costs in hot climates like New Orleans, LA. Spray foam seals all gaps and cracks that allow conditioned air to escape, which is the primary cause of high AC bills. Most homeowners in hot climates report 20–30% reductions in cooling costs after spray foam installation.
Is spray foam insulation worth the cost?
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost in New Orleans, LA?
In New Orleans, LA and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic in New Orleans costs $2,000–$6,000. Most New Orleans homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor in New Orleans, LA?
When searching for a spray foam contractor in New Orleans, LA, look for ones who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified New Orleans contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors in New Orleans for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
